You may have seen that this has already been tried, and found

Sorry, I cannot reply to all posts in a few hours.
I hope you realize how... local that patch it. Sure, it makes the 18 MB
json file example (and only that example) slightly better. But on my
machine I still see Emacs stuttering when leaning on C-v, I still see
delays when searching through the file with C-s, and so forth. And of
course with larger files the delays become more and more significant.
With a 300 MB json file I have to wait about 30 s after pressing M->.
